Dev Build 2119 is out now, with a few polish related changes.
There are a few more key bindings for code folding now, notably Ctrl+K,Ctrl+ to fold everything at that indentation level: Ctrl+K,Ctrl+1 will fold everything (Command+K,Command+ on OS X).
Vintage ctrl key bindings are now gated by the vintage_ctrl_keys setting, which is false by default on Windows and Linux, but true on OS X. This prevents the vintage key bindings from overriding the regular ctrl key bindings on these platforms.
Sidebar headings also no longer have disclosure buttons shown next to them, which makes better use of the horizontal space in the side bar. This is controlled by the indent_top_level property in the theme.
